As well-known, the type of grinding media and its environment dictate particle size, surface and shape characteristics. To address this, many papers in the literature showed this contribution for different parameters such as grinding media as ball, rod and autogeneous [18,19], disc mill [16], ball size [20] and blasting pressure [9,21,22].Web

The crushed ore is then transported to the mill site for crushing, grinding, classification and concentration. The second stage, grinding, is a wet operation which requires initial flotation and water to make a slurry. The hydrocyclone operates between each grinding operation to classify the type of particles: fine or coarse (Long et al., 1998).Web
